8-Ch Ethernet Relay Module
Ethernet Port Communication, Modbus Protocol, PoE Power Supply
Features
This product is an industrial 8-ch relay module controlled via Ethernet port, adopts Modbus RTU/Modbus TCP protocols, supports PoE power supply, also comes with an ABS rail-mount case.
The Modbus POE ETH Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirements.
- Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically
- Supports DC 7~36V wide range power input and PoE power supply
- Supports relay control through MQTT protocol, comes with Alibaba Cloud MQTT application demo
- Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High-quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail-mounted ABS case, easy to install, safe to use
- 4 LEDs and Network indicators for indicating the MCU status and signal transceiving status
